The difference between a person's resting and target heart rate reflects the amount of work the heart must do to meet the increased demands of the body when exercising.
It usually slows down
No, resting allows you to resume your normal breathing, but respiration is really energy.
it decreases
The distance between the resting position and the crest of a wave is equal to the distance between the resting position and the trough of the wave. This is because waves are symmetric, with equal distances above and below the resting position.
About 10-12 Beats Per Minute
Your heart rate, or pulse, is the number of times your heart beats in a minute. Depending on your age and level of physical fitness, a normal resting pulse ranges from 60 to 80 beats per minute. Your breathing rate is measured in a similar manner, with an average resting rate of 12 to 20 breaths per minute. Both your pulse and breathing rate increase with exercise, maintaining a ratio of approximately 1 breath for every 4 heartbeats.
The usual resting pulse for an adult is 60 to 100 beats per minute. Certain illnesses can cause your pulse to change, so it is helpful to know what your resting pulse is when you are well.
While resting, the body primarily uses stored energy in the form of carbohydrates and fats to fuel basic bodily functions like breathing, circulation, and maintenance of body temperature.
Respiratory rate, which is also called breathing rate, is the same for teens as adults. There should be between 12 and 16 breaths per minute. However, as a child enters later teens his/her resting breathing rate should decrease slightly from what it was in his/her early teens.
The minimum resting energy expenditure of an awake alert person is referred to as resting metabolic rate (RMR). It represents the amount of energy required to maintain basic physiological functions such as heartbeat, breathing, and body temperature while at rest.
